Medical toxicology is a medical subspecialty focusing on the diagnosis, management and prevention of poisoning and other adverse health effects due to medications, occupational and environmental toxicants, and biological agents. Medical toxicologists are involved in the diagnoses and treatment of acute or chronic poisoning, adverse drug reactions (ADR), overdoses, envenomations, and substance abuse, and other chemical exposures.
Medical toxicologists are generally seen in emergency departments, intensive care units, and other in-patient units where they provide direct treatment and bedside consultation of acutely poisoned adults and children. Moreover, they also attend medical schools, universities, and clinical training sites where they teach, research, and provide advanced evidence based patient care. Medical toxicologists are an asset to industry and commerce where they contribute to pharmaceutical research and drug safety.
